Your company has a private cloud that is managed by using a System Center 2012 infrastructure. The
network contains seven servers. The servers are configured as shown in the following table.

You need to recommend a solution to apply Windows updates to the virtualization hosts.
The solution must meet the following requirements:
Approve Windows updates from the VMM Administrator Console.
Store information about Windows update installations in Configuration Manager reports.
What should you do first?

A.
From the VMM Administrator Console, add Server6 as a host server, and then install the
Configuration Manager agent on Server1.

B.
On Server7, install Windows Server Update Services (WSUS), and then install the Configuration
Manager agent on Server1.

C.
On Server7, install Windows Server Update Services (WSUS), and then install the Configuration
Manager agent on all of the virtualization hosts.

D.
From the VMM Administrator Console, add Server6 as an update server, and then install the
Configuration Manager agent on all of the virtualization hosts.

Explanation:
The requirements need a WSUS server.
Server 7 is the most appropriate server to install WSUS.

A configuration manager agent is required to store information about Windows update installation
in the Configuration Manager reports.

Step 1: Install and Configure a Software Update Point
The software update point is required on the central administration site and primary sites to enable
software updates compliance assessment and to deploy software updates to clients.
The software update point is optional on secondary sites.
The software update point site system role must be created on a server that has WSUS installed.
The software update point interacts with the WSUS services to configure software update settings
and request synchronization of software updates metadata.
When you have a Configuration Manager hierarchy, install and configure the software update point
on the central administration site first, then on child primary sites, and then optionally on secondary
sites.
When you have a stand-alone primary site (no central administration site), install and configure the
software update point on the primary site first, and then optionally on secondary sites.
Some settings are only available when you configure the software update point on a central
administration site, or stand-alone primary site, and there are different options that you must
consider depending on where the software update point is installed.
